Customs duty
A customs duty is a tariff or tax which a country imposes on goods when they are transported across international borders. Customs Duties are used to protect countries' economies, residents, jobs, and environments, by limiting the flow of imported merchandise, especially restricted and prohibited goods, into the country. The Customs duty rate is a percentage determined by the value of the article purchased in the foreign country and not based on quality, size, or weight. U.S. customs duties are listed in the Harmonized Tariff Schedule of the United States.
Search Primer
Term list: Separate terms with spaces, not commas or semicolons.
Multi-word term: Place inside quotes to ensure an exact match (e.g. "China import").
Acronyms: Use all capital letters to ensure the search is not looking for that letter sequence instead.
Required term: If a term must be included in any resulting articles, prefix it with a plus sign (e.g., +CBP).
Excluded term: If a term should be excluded from any articles being found, prefix it with a minus sign (e.g., -ruling).
Singular form: Always use the singular form when doing multi-word terms (e.g. "russian export control" instead of "russian export controls").
Shortest word form: When you have different word forms in a quoted (multi-word) term, you want to only include the shortest version if it is the last part of the expression (e.g., "entity list" instead of "entity listing" or "entity listed").
